Decay ofSb115

${\mathrm{Sb}}^{115}$ (32 min) decays by electron capture and positron emission to ${\mathrm{Sn}}^{115}$, the positron branch accounting for (12±3)% of the disintegrations. Of the total disintegrations 94% lead directly to a previously known 499-kev level in ${\mathrm{Sn}}^{115}$. The remaining 6% of the disintegrations are to an excited state in ${\mathrm{Sn}}^{115}$ and are followed by two gamma rays in cascade whose energies are 980 kev and 1240 kev, respectively. The crossover gamma ray of 2220 kev has also been seen, with an intensity equivalent to 1% of the disintegrations. The cascade and crossover gamma rays lead to the 499-kev level and coincidences have been observed between these gamma rays. An upper limit of 0.4% was obtained for a beta branch from ${\mathrm{In}}^{115m}$ to the 499-kev level in ${\mathrm{Sn}}^{115}$. These levels in ${\mathrm{Sn}}^{115}$ seem to be too high in energy to correspond to the predicted low-lying levels in ${\mathrm{Sn}}^{115}$ of Kisslinger and Sorensen.
